I love the idea of a dance card at each girl's place setting at a wedding. You could create a short playlist, maybe 5-7 songs, print them on the dance card and have the band announce the songs. It would be such a fun souvenir and a great way to encourage people to get on the dance floor. Plus I love the iconography of these dance cards from the 20s and 30s, the drawings are divine.
